Because I had gotten PetzA (I fell into the temptation and decided to try it out, and it's awesome because it lets me breed lots and lots of petz fast), I have completed my petz breeding! Yes!
If you notice, all the petz are named according to their siblings (save for the 1st gen), so you can tell who's a sibling of who. I also drew lines to the breeding pairs. I made two breeding pairs per generation. I never breed siblings together, and I suppose 'cousins' aren't that bad.
Here's a picture of the madness!
I intend to draw pictures of some of the hybrids that I have obtained. :3
